BATTESE REVOIR, OF GEDDES, NEW YORK.

FlLTE R FOR THE SUCTION-PIPES OF PUMPS.

SPECIFICATION forming part of Letters Patent No. 362,314, dated May a, 1887.

Application liled January 7, 1886. Serial No.187,887. (No model.) I

To all whom it may concern.-

Be it known that I, BATTESE REVOIR, of

Geddes, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Filters for Suction- Pipes of Pumps, of which the following,takcn in conneclion with the accompanying drawings, is a full, clear, and exact description.

This invention consists in a novel construction of a filter specially designed for attachment to the suctionpipe of a pump.

In the accompanying drawings, Figure I is a side view of my invention.

Fig. III is a plan view of the inner side of the cover which, by braces connected therewith, sustains. the removable diaphragm in position; and Fig. IV is a transverse section on line a: at, Fig. II.

Similar letters of reference indicate corresponding parts.

A represents the body of the filtering-case, composed of a metallic cylinder. 1 To opposite ends of said cylinder are applied removable covers B (J. The cover B is provided on its exterior with a nozzle, a, for attachment to the suction-pipe D of a pump. The cover G is provided with an opening, I), for the inlet of water to the interior ofthe ease, and around said opening is a cup, 0, or suitable holder for a sponge.

Across the interior of the case, some distance from the ends thereof, are arranged two perforated diaphragms, d and e. The diaphragm d, which is nearest the cover B, is rigidly secured to the case, and the other diaphragm, e, is removable. Between the said diaphragm is placed a packing, f, of suitablefiltering material, which is held in position by braces l I, attached to the cover 0, around the opening I), and extending convergent therefrom and pressing on the center of a stiff spider,'- n,

- placed across the diaphragm c, said spider serving to brace the diaphragm and to transmit the pressure to the margin thereof.

Fig. ll-is a 1011- The described filter is attached to the lower 5 end of the suctionpipc D, as aforesaid,'and is to be submerged in the well or cistern. When suction is produced in the pipe D, the water is drawn through the sponge in the cup 0 and through the filtering material f in the case A, and thereby becomes clarified before it enters the pipe D. Then it is desired to said cover. 1

Having described my invention, what I claim as'new, and desire to secure by Letters Patent, is-- The combination. ina filter for suctionpumps, of the cylinder A, connecting with the pump at one end by means of the pipe D, the stationary diaphragm (Z and removable diaphragm e, and an intermediate Hllingspace, the spider n bearing at its center and the ends of its arms against the removable diaphragm,

' the braces L, having a common bearing against the center of the spider, and the movable head. 0, carrying the said braces and having a central induction-apcrture and sponge-enp,. the whole arranged substantially in the manner and for the purposes specified.

In testimony whereofl have hereunto signed my name and altixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 19th day of December, 1885.
